Clinoptilolite-Ca – heulandite-Ca solid solution series
Clinoptilolite-K – heulandite-K solid solution series
Clinoptilolite-Na – heulandite-Na solid solution series
Use of clinoptilolite in industry and academia focuses on its ion exchange properties having a strong exchange affinity for ammonium (NH4+). A typical example of this is in its use as an enzyme-based urea sensor. It is also used as fertiliser and sold as a deodorizer in the form of pebble-sized chunks contained in a mesh bag.
Research is generally focused around the shores of the Aegean Sea due to the abundance of natural clinoptilolite in easily accessible surface deposits.
The name is derived from the Greek words klino (κλίνω; “oblique”), ptylon (φτερών; “feather”), and lithos (λίθος; “stone”).
